Calculated wall shear stress (WSS) parameters from computational fluid dynamics (CFD) analysis.

Short name	Description	Formula
WSSmax	Maximum in time and space of the WSS magnitude	$\text{Time}\text{Max}\left(\text{Spatial}\text{Max}\left(\left|\text{WSS}\right|\right)\right).$
WSSmean	Maximum in time of the spatial mean of the WSS magnitude	$\text{TimeMax}\left(\frac{{\displaystyle \sum {\left|\text{WSS}\right|}_i·A_i}}{{\displaystyle \sum A_i}}\right).$
		Where i refers to the surface mesh element at the aortic wall and A i is the area of the surface mesh element. The mean value was calculated over each sub-segment
WSSTmean Max	Mean in time of the spatial maximum of the WSS magnitude	$\frac{{\displaystyle \sum {\left(\text{SpatialMax}\left(\left|\text{WSS}\right|\right)\right)}_j}}{j}$
		Where j is the number of time points
TAWSS	Time average of the magnitude of the WSS	$\text{TAWSS}=\frac{1}{T}{\displaystyle \underset{0}{\overset{T}{\int }}\left|\text{WSS}\right|\text{d}t}$
TAWSSmax	Spatial maximum of the TAWSS	$\text{SpatialMax}\left(\text{TAWSS}\right)$
TAWSSmean	Spatial mean of the TAWSS	$\frac{{\displaystyle \sum {\text{TAWSS}}_i·A_i}}{{\displaystyle \sum A_i}}$
